UNITED STATES PATENT OFFICE FREDERICK O; DAMM', OF CLEVELAND, OHIO.

MACHINE FOR MAKING BIRD-TARGETS.

S?ECIFICATION forming part of Letters Patent No. 434,107, dated August12,1890.

Application filed June 11, 1889. Serial No. 313,831. (No model.)

To all whom it may concern:

Be it known that I, FREDERICK O. DAMM, of Cleveland, in the county ofOuyahoga and State of Ohio, have invented certain new and usefulImprovements in Machines for Making BirdTargets; andIdo hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use the same.

My invention relates to an improved machine for making bird-targets; 'and it consists in certain features of construction and in combination ofparts, hereinafter described, and pointed out in the claims.

In the accompanying drawings,Figure 1 is a plan view of a machineembodying my invention. Fig. 2 is a plan view thereof with the bedremoved. Fig. 3 is a side elevation, in longitudinal section, throughthe center of the machine. Fig. 4 is an elevation in section of thedogging device. Fig. 5 is an elevation, partly in section in detail, ofthe collar and lever for actuating'the friction-clu tch. Figs. 6, 7, andS are side elevations, respectively, of cam-disks O O and O.

A represents a bed-plate mounted on legs a. Suitable hangers A dependfrom the bed for supporting, respectively, shafts B, O, and D, theseshafts being arranged crosswise of the bed, substantially as shown inFig. 2. The driving-shaft B is provided with cone-pulley b for receivingthe driving-belt, by means of which the speed of the machine isregulated. On shaft B is mounted pinion B, engaging gear 0 of shaft 0.On this latter shaft are also mounted cam-disks O O and 0 On this shaftis also mounted a friction-clutch, the male member E of which is keyedfast to the shaft O,the other member E being mounted loosely on theshaft. Member E of the clutch is integral or rigidly attached tobandwheel The hub of the members E and E has a circumferential groove inwhich fits loosely the collar 6, this collar being made in halves andbolted together, substantially as shown in Fig. 5. This collar haslaterally-pro jecting trunnions e, that are pivoted in rings 6 thelatter being rigidly secured to the two sections of lever F. Thisleveris pivoted at f,

and the free end of the lever is connected with spring F. The tension ofthis spring is suflicient to operatively close the friction-clutch. Themembers of this clutch are held apart against the action of the springduring three quarters of a revolution of shaft 0 by means of an arm Fand roller f ,the arm being connected with lever F and the rollertraveling on the laterally-projecting rim of disk O This rim is cut awayat c, leaving a notch or depression that extends one quarter way aroundthe disk, and when roller f is opposite this notch the tension of springFoperatively'closes the clutch, so that band-wheel E makes aquarter-revolution for each entire revolution of shaft O. A belt f leadsfrom band-wheel E to the band-wheel d, these bandwheels being of equaldiameter, and the latter being mounted on shaft D. On this shaft is alsomounted beveled pinion cl, the latter engaging beveled gear g. This gearis keyed fast to the upright shaft G. This shaft extends up through thebore A of hub A of the bed. On the upper end of this shaft ismounted theintermittentlyrevolving table H, the under side of the table engagingthe upper end of hub A On the face of the table is a series of molds h,in which the bird-targets are compressed by means of a drop-plunger I.Any number of these molds may be placed on a table, (more or less,)according to the size of the machine. In Fig. 1 sixteen such molds areshown, these molds being placed at equal intervals in concentric orderwith the axis of the table. The revolving table must make one revolutionwhile shaft 0 is making as many revolutions as there are molds on thetable, and in the present instance the shaft would make sixteenrevolutions while the table was making one revolution. By separatingthemembers of the friction-clutch in the manner already described the tableremains at rest fora moment while the plunger is doing its work.

The mechanism for operating the plunger I is as follows: J is a standardsecured to the upper face of the bed, this standard having a lateral armJ projecting over the table. Through suitable holes in this armreciprocate the plunger I and rod I',these two members being rigidlyconnected by tie-bars 1 The lower end of rod I is provided with a roller1:, that travels on the face of cam C Rod 1 I and the attached plunger.are gradually elevated by means of the cam until the molds, and a dogK, having a conical end for.

successively engaging these holes when the table is in position and oneof the molds directly under the plunger. Mechanism for operating the dogis shown more clearly in Fig. 4. The lower end of the dog is pivoted tolever L, the latter being fulcru med at m to hanger M, and the dogoperating through a hole in the bed. The free end of the lever L isprovided with a roller Z, the latter traveling on the face of cam-disk 0A spring L is connected with the free end of lever L for depressing thesame and thereby elevating the dog Whenever notch O of the camdisk is inposition to receive roller Z. The parts are so timed that the dogengages a hole 71/ in the table just as the friction-clutch is openedand the table is in position, with one of its molds under the plunger,and the dog remains in position holding the table stationary while theplunger is doing its work, after which, by the action of cam 0 the dogis withdrawn from its engagement with the table, and this occurs just asthe frictionclutch is closed for revolving the table.

There is no special means or mechanism shown for feeding the material tothe molds or for removing the target from the molds, such mechanismbeing reserved for a separate application for Letters Patent. Themachineisentirelyoperative,however,with handlabor for feeding thematerial to the mold and for removing the target, and with suchhand-labor the machine is a great advance in the art of makingbird-targets. i

What I claim is-- 1 1. The combination, with a table carrying a seriesof molds and gearing for imparting a rotary motion to said table, of ashaft, a clutch thereon, driving mechanism connected with the loosesliding section of the clutch for actuating the table-gearing, anddevices for automatically opening and closing the clutch tointermittingly rotate the table, substantially as set forth.

2. The combination, with a table, gearing for rotating the same, molds,friction-clutch, motion-transmitting devices connecting the tablegearing and sliding section of the clutch, and a lever for sliding onesection of the clutch, of a spring for actuating the lever in onedirection and a cam for moving the lever inthe opposite direction, theparts being timed to intermitttingly rotate the table the distance fromone mold to another, substantially as set forth.

3. In a bird-target machine, the combination, with a rotary tablecarrying molds, a constantly-rotating shaft having a clutch thereon, andpower-transmitting devices actuated by the loose section of the clutchfor rotating the table, of a plunger actuated by the constantly-rotatingshaft, and a dog for looking the table against movement, also actuatedby said shaft, substantially as set forth.

In testimony whereof I sign this specification, in presence of twoWitnesses, this 4th day of June, A. D. 1889.
